When I drive my car on petrol it seems that it misfiring some times and when I start it on idle the rpm are high, but when I touch the wiring which comes from the computer the rpm becomes normal and during the drive when the wire cable misplaced it start misfiring again. I am unable to understand that which wire is loos so that I could fix it.

This sounds like a classic tune up with ignition coils problem which are normal service items so we should start there first. Also, do you have a check engine light on? If so we should run the codes.
